YF-3 5L Fire alarm Control Panel

Fire Alarm Control Panel YF-3 5L Merek Yun Yang


Product Functions

  • Integrated circuit indicators: each circuit is equipped with monitoring functions on fire, circuit break and short circuit, respectively.
  • The fire alarm circuit and the indicator circuit are able to detect circuit break and offer protection against short circuit.
  • The system always keeps close watch over battery charging and the voltage of the stand-by battery to ensure that the panel functions well in all circumstances to prevent any disaster.
  • Each circuit is equipped with a testing button to ensure the normal function of initiating circuits.
  • Operations are controlled by a key to prevent false alarms caused by accidental touch.
  • Digital error detection for voltage source: whenever a voltage error is detected by the system, an error alarm will sound and an indicator will light on.
  • Two-stage alarm delay function to prevent false alarms: When the detector activates for the first time, the system will automatically reset the detector. If another signal is received in a short period of time after that, the system will then confirm that there is a fire.


  • “Self-Reset" mode and "Non Self-Reset" mode are available for operators to set if they want the panel to automatically reset the fire alarm signals after the fire extinction or not.
  • Separate control switches for main audio, local audio, indicator, and relay output.
  • There is an error indicator above each switch.
  • Digital electronic switches are used for dust proofing and a long service life.
  • Equipped with many function indicators: alarm, power supply, and circuit connection fault.
  • Build-in buzzer with dust proofing and long service life.
  • Warning announcement is always made automatically with loud sound.
  • Many zone circuit configurations are available: 1L, 2L, 4L, 5L, 8L, 12L, 16L, 20L, 24L.
